Bylgja

This lady is quite fierce in and out of water, able to freely switch between a tail and legs as well as changing her teeth to make her bites worse. She is at her fastest in the water but is super strong in and out of it. Her fins may not look strong but they are far from fragile or easily ripped and her claws are incredibly sharp. She also possesses some power over water and has magic seashells that she can summon water from if needed.
